具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
本申请实施例的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一目标对象和第二目标对象等是用于区别不同的目标对象，而不是用于描述目标对象的特定顺序。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。例如，多个处理单元是指两个或两个以上的处理单元；多个系统是指两个或两个以上的系统。

S801，通过多个扬声器播放音频信号；其中，多个扬声器对称布局、且数量大于或者等于3。
音频播放装置例如可以是平板、车载音响系统等，可以通过该音频播放装置的多个扬声器播放音频信号，以检测多个扬声器是否异常。在一种可选的示例中，音频播放装置通过多个扬声器播放的音频信号，可以是指定音频信号也就是指定音源，例如可以是谐振频率(F0)±100Hz的单频信号，或频率变化范围属于[20Hz，20KHz]的扫频信号。谐振频率(F0)指扬声器从低音域开始振动时，振动板最强烈振动所在点对应的频率。单频信号是由简谐振动产生的频率固定、并按正弦变化的声波信号。扫频信号也就是正弦扫频信号是指在一定的频段范围内频率连续变化的信号。在一种可选的示例中，音频播放装置通过多个扬声器播放的音频信号，可以是预先制定的声音信号，例如，用户(如手机用户)制定的音频信号(通过手机的扬声器外放的音乐)。
本申请实施例中，扬声器播放音频信号时的无异常运行状态可以预先确定，进而音频播放装置可以预先存储用于指示每个扬声器无异常的运行状态的标准状态信息。这样，音频播放装置通过每个扬声器播放音频信号时，可以直接根据预先存储的标准状态信息确定该扬声器播放是否异常，更加便捷、准确。
另外，上述可选示例中的单频信号和扫频信号属于人耳可听范围，且被播放时扬声器的运行状态能够被检测，可以提高对扬声器播放异常的检测准确度，提高后续扬声器运行状态调整的准确度，进一步减少扬声器播放异常引起的声场效果异常，提高用户体验。预先制定的声音信号为用户制定的音频信号，例如用户播放的音乐等，播放该声音信号时用户存在音频体验需求，因此，基于该声音信号检测可以及时提高用户的音频体验。
在一种可选的实施方式中，音频播放装置可以在启动时执行上述步骤S801。或者，音频播放装置可以在启动时，展示询问是否开启校准的用户交互界面，当通过该用户交互界面接收到开启校准的指示信息时，执行上述步骤S801。或者，音频播放装置可以在运行过程中周期性展示询问是否开启校准的用户交互界面，当通过该用户交互界面接收到开启校准的指示信息时，执行上述步骤S801。本申请实施例对上述步骤S801的执行条件不作限制。
另外，多个扬声器在音频播放装置上的布局可以参见本申请图1至图4的描述，此处不再赘述。音频播放装置可以参见本申请图5至图7b的描述，此处不再赘述。
S802，检测每个扬声器对音频信号的运行状态，得到检测结果。

在一种可选的实施方式中，在音频播放装置配置有麦克风(MIC)的情况下，音频播放装置可以利用MIC采集音频播放装置播放的音频信号，得到第一声场音频信号；确定第一声场音频信号与预先存储的第二声场音频信号间的差异；若差异大于预设信号差异，确定检测结果为播放异常。在一种可选的实施方式中，音频播放装置利用MIC采集音频播放装置播放的音频信号，得到第一声场音频信号，可以包括：音频播放装置控制每个扬声器独立播放音频信号，利用MIC分别采集每个扬声器播放的音频信号，得到该扬声器的第一声场音频信号。相应地，针对每个扬声器，确定该扬声器的第一声场音频信号与该扬声器的预先存储的第二声场音频信号间的差异；若差异大于预设信号差异，确定该扬声器的检测结果为播放异常。
示例性的，上述麦克风的数量可以为多个，配置位置可以是音频播放装置的每个扬声器附近。或者，麦克风的数量可以为一个，配置位置可以是音频播放装置的全部扬声器的中间位置，例如，本申请图4所示音频播放装置的扬声器401和扬声器402中间，且与扬声器403和扬声器404间的距离相同。第一声场音频信号相当于当前状态信息。第二声场音频信号相当于标准状态信息，是音频播放装置的扬声器的播放无异常时，上述麦克风采集的音频播放装置播放的音频信号。第二声场音频信号可以由音频播放装置的厂商预先采集并存储在音频播放装置中。第一声场音频信号与预先存储的第二声场音频信号间的差异，可以是信号的波形、频率等信号特征的差异，和/或可以是响度的差异。
在一种可选的示例中，如本申请图7a和图7b所示，音频播放装置的每个扬声器可以配置一个功率放大器。音频播放装置可以从每个功率放大器中获取该功率放大器对应的扬声器的当前输入功率；获取每个扬声器的当前音量级别；根据每个扬声器的当前音量级别，从每个扬声器的预存的功率配置表中查找当前音量级别对应的标准输入功率；确定每个扬声器的当前音量级别与所查找的标准输入功率的差异；若差异大于或者等于预设功率差异阈值，确定检测结果为播放异常，若差异小于预设功率差异，确定检测结果为播放无异常。预存的功率配置表可以包括：每级音量对应的每个扬声器的标准输入功率。标准输入功率用于指示音频播放装置的扬声器播放无异常时每级音量对应的每个扬声器的输入功率。举例而言，音频播放装置为一级音量，此时扬声器的标准输入功率为第一功率；音频播放装置为二级音量，此时扬声器的标准输入功率为第二功率。
在一种可选的示例中，如本申请图7a和图7b所示，音频播放装置的每个扬声器可以配置一个功率放大器。音频播放装置可以从每个功率放大器中获取该功率放大器对应的扬声器的当前理论振幅和当前输入功率；查找每个扬声器的预存的标准理论振幅与每级功率的对应关系，得到当前输入功率对应的标准理论振幅；确定每个扬声器的当前音量级别与所查找的标准理论振幅的差异；若差异大于或者等于预设理论振幅阈值，确定检测结果为播放异常，若差异小于预设理论振幅差异，确定检测结果为播放无异常。标准理论振幅可以包括：音频播放装置的扬声器播放无异常时每级输入功率对应的每个扬 声器的理论振幅。每级功率对应的每个扬声器的理论振幅可以包括：音频播放装置的功率放大器(例如可以是智能功率放大器SmartPA)根据每级功率对应的该扬声器的电信号计算得到的该扬声器的振幅。
在一种可选的示例中，音频播放装置的每个扬声器可以配置振动测量传感器(如声电式传感器、小型加速度传感器等)，也就是说，音电传感器、小型加速度传感器与音频播放装置的扬声器一一对应，安装在相应扬声器附近，例如与相应扬声器的距离小于或者等于距离阈值。相应地，音频播放装置可以通过每个振动测量传感器，测量该振动测量传感器对应扬声器的当前振动测量参数。其中，每级功率对应的扬声器振动测量参数可以包括以下至少之一：测量每级功率对应的扬声器的振动频率和振动幅度，得到的振动频率测量值和振动幅度测量值。音频播放装置可以从每个功率放大器中获取该功率放大器对应的扬声器的当前输入功率；查找每个扬声器的预存的标准测量振幅与每级功率的对应关系，得到当前输入功率对应的标准测量振幅；确定每个扬声器的当前音量级别与所查找的标准测量振幅的差异；若差异大于或者等于预设测量振幅阈值，确定检测结果为播放异常，若差异小于预设测量振幅差异，确定检测结果为播放无异常。标准测量振幅可以包括：音频播放装置的扬声器播放无异常时每级输入功率对应的每个扬声器的测量振幅。
音频播放装置根据当前输入功率确定的播放异常可以指示扬声器响度异常，例如响度大于标准响度也就是响度偏大，响度小于标准响度也就是响度偏小。音频播放装置根据当前理论振幅和当前振动测量参数确定的播放异常可以指示扬声器频率异常，例如频率大于标准频率也就是频率偏高，频率小于标准响度也就是频率偏低。当前输入功率、当前理论振幅和当前振动测量参数中的任一种为0时确定的播放异常，可以指示扬声器损坏异常，例如，扬声器无声，线路断开等异常。
可以理解的是，音频播放装置可以检测上述扬声器的当前输入功率、当前振动理论参数和当前振动测量参数中的至少之一，作为当前状态信息，具体可以根据应用需求设置。相应地，音频播放装置的结构适用于所测量的参数，对相应结构的描述可以参见上述关于获取当前状态信息的实施例的描述，此处不再赘述。
示例性的，音频播放装置中可以预先存储标准状态信息例如可以是初始参数，也就是说，音频播放装置中用于实现本申请实施例提供的扬声器控制方法的内置算法可以预先植入指示扬声器无异常的运行状态的初始参数。其中，初始参数可以包括如下参数中的至少之一：每个位置的扬声器的功率配置表、每级功率对应的扬声器理论振幅，每级功率对应的扬声器振动测量参数。
另外，音频播放装置可以同时检测每个扬声器对音频信号的运行状态。或者，音频播放装置可以回环检测也就是逐一检测每个扬声器对音频信号的运行状态，例如，参见图4，音频播放装置可以依次检测扬声器401、扬声器403、扬声器404和扬声器402的运行状态，或者依次检测扬声器401、扬声器402、扬声器404和扬声器403的运行状态，即以“环路”的形式检测。本申请实施例对此不作限制。

下面结合图9和图10，以示例性说明的方式对S803进行具体描述，以便于理解。
示例性的，图9是本申请实施例提供的一种扬声器控制过程示意图之一，该过程以本申请实施例提供的扬声器控制方法应用于图7a所示的音频播放装置700为例，包括如下步骤：
S901，检测是否调整扬声器的运行状态；若调整，执行S902；若不调整，执行S905。
上述S901与本申请图8实施例的S801至S802为相似步骤，对于相同部分此处不再赘述，详见本申请图8实施例的已有描述。区别在于S901中：
音频播放装置获得的检测结果，具体可以是异常原因，异常原因不为空则指示检测结果为播放异常，异常原因为空则指示检测结果为播放无异常。示例性的，异常原因可以包括可校准异常或者不可校准异常。其中，可校准异常指通过调整播放异常的扬声器的运行状态能够解决的异常，例如，扬声器的响度异常、频响异常等异常。不可校准异常指无法通过调整播放异常的扬声器的运行状态解决的异常，例如，扬声器的损坏异常。对于扬声器的响度异常、频响异常和损坏异常，可以参见上述对S802的说明中的已有描述。
若异常原因为可校准异常，则播放异常的扬声器数量无论为多少，均可调整扬声器的运行状态。举例而言，针对配置N(N≥4)个扬声器的音频播放装置，在M(M≤N)个扬声器异常、且为可校准异常，可以执行S902。参见图9，扬声器706的异常为响度偏小，扬声器705的异常为响度偏大。
S902，确定播放异常的扬声器标识“705”和“706”。

示例性的，图10是本申请实施例提供的一种扬声器控制过程示意图之一，该过程以本申请实施例提供的扬声器控制方法应用于图7a所示的音频播放装置为例，包括如下步骤：

上述S1001与本申请图9实施例的S901为相似步骤，对于相同部分此处不再赘述，详见本申请图9实施例的已有描述。区别在于S1001中：若异常原因为不可校准异常，且播放异常的扬声器数量小于或者等于音频播放装置的扬声器总数的一半时，才可调整 扬声器的运行状态，也就是才能构建新声场。举例而言，针对配置N(N≥4)个扬声器的音频播放装置，若K(K＜N/2)个扬声器异常、且为不可校准异常，可以执行S1002。若异常原因为不可校准异常，且播放异常的扬声器数量大于音频播放装置的扬声器总数的一半时，执行S1005，输出扬声器报修提醒。如图10所示，N/2＝4/2＝2，则播放异常的扬声器数量大于2时，输出扬声器报修提醒。

另外，音频播放装置通过多个扬声器播放的音频信号为用户选择的音频信号，例如音频播放装置对音乐、电影、有声读物等音频信号通过扬声器外放时，扬声器播放不同内容的音频信号时的当前状态信息通常存在较大差异。此时，音频播放装置可以按照预设周期执行S802，以获得更加准确的运行状态，得到更加准确的检测结果。
S1002，确定播放异常的扬声器标识“707”。
上述S1002与本申请图9实施例的S902为相似步骤，对于相同部分此处不再赘述，详见本申请图9实施例的已有描述。区别在于S1002中播放异常的扬声器标识为“707”。
S804，根据播放异常的异常原因和扬声器标识，调整多个扬声器中至少一个的运行状态至目标状态；其中，目标状态用于构建具有立体声或环绕声效果的声场。
音频播放装置确定播放异常的异常原因和扬声器标识后，可以根据播放异常的异常原因和扬声器标识，调整音频播放装置中多个扬声器中至少一个的运行状态至目标状态。其中，多个扬声器中至少一个为音频播放装置的全部扬声器中，用于补充异常扬声器的声音效果的扬声器。
在一种可选的实施方式中，异常原因为可校准异常时，多个扬声器中至少一个可以包括播放异常的扬声器。也就是说，对于可校准异常的异常扬声器，直接调整该异常扬声器的运行参数即可补充异常扬声器的声音效果以解决播放异常，从而构建具有立体声或环绕声效果的声场。相应地，音频播放装置根据播放异常的异常原因和扬声器标识，调整音频播放装置中多个扬声器中至少一个的运行状态至目标状态，可以包括：音频播放装置根据异常扬声器的当前状态信息与标准状态信息的差异，确定目标状态对应的运行参数调整量，根据运行参数调整量和扬声器标识调整多个扬声器中至少一个的运行参数。
示例性的，运行参数调整量例如可以是功率补偿值、增益补偿值和EQ(Equalize，均衡效果器，用于调节音效)补偿值等参数。音频播放装置根据功率补偿值、增益补偿值和EQ补偿值，可以对响度异常偏大的扬声器进行降功率，降增益，EQ调整的处理；对响度异响偏小的扬声器进行升功率，升增益，EQ调整的处理。这样，可以及时完成异常处理，使音频播放装置恢复到初始的播放水平。举例而言，如图9所示，扬声器控制方法的处理过程还可以包括：S903，处理器701指示扬声器705下调增益，扬声器706上调增益。
在一种可选的实施方式中，异常原因为不可校准异常时，多个扬声器中至少一个可以包括音频播放装置的全部扬声器中，除播放异常的扬声器以外的扬声器。也就是说， 对于不可校准异常的异常扬声器，可以调整音频播放装置中除该异常扬声器以外扬声器的运行参数，来补充异常扬声器的声音效果以解决播放异常，从而构建具有立体声或环绕声效果的声场。相应地，音频播放装置根据播放异常的异常原因和扬声器标识，调整音频播放装置中多个扬声器中至少一个的运行状态至目标状态，可以包括：音频播放装置关闭与异常扬声器位置对称的第一扬声器，根据异常扬声器的标准运行参数和第一扬声器的标准运行参数，确定目标状态对应的运行参数调整量，根据运行参数调整量和扬声器标识调整第二扬声器的运行参数；其中第二扬声器为音频播放装置的扬声器中，除异常扬声器和第一扬声器以外的扬声器。
示例性的，如图10所示，扬声器控制方法的处理过程还可以包括：S1003，处理器701指示扬声器706关闭，扬声器704和扬声器705上调增益。也就是说，扬声器707为播放异常的扬声器，扬声器706为第一扬声器，扬声器704和扬声器705为第二扬声器。处理器701向与扬声器707位置对称的扬声器706发出指令，关闭扬声器706的信号输入，同时处理器701控制其余两路扬声器也就是扬声器704和扬声器705的功率放大器根据运行参数调整量，加大增益，提升输入功率及进行EQ调整。
在一种可选的实施方式中，音频播放装置在检测到扬声器异常后，还可以检测该扬声器对应的功率放大器是否异常，若异常，则建立该功率放大器与同组功率放大器间的电流通路。其中，每两个间距最短的功率放大器可以作为一组功率放大器。或者，每两个位置对称的扬声器分别对应的功率放大器可以作为一组功率放大器。每两个功率放大器可以作为一组功率放大器，以降低控制和硬件成本。本申请实施例对此不作限制。
示例性的，音频播放装置可以检测播放异常的扬声器对应的功率放大器反馈的电信号是否异常，若异常，确定该功率放大器异常。功率放大器的异常例如可以是功率放大器停止工作。如图9或者图10所示，功率放大器PA1和功率放大器PA3作为同组功率放大器，建立有连通和断开可控的连接。功率放大器PA2和和功率放大器PA4作为同组功率放大器，建立有连通和断开可控的连接。当同组功率放大器中有一个异常(如PA4)时，音频播放装置指示该连接连通，也就是建立同组功率放大器间的电流通路。这样，同组功率放大器中无异常的功率放大器(如PA3)可以控制两路扬声器的工作，以解决功率放大器异常引起的扬声器异常。举例而言，本实施例相当于音频播放装置将异常扬声器(如扬声器707)的运行状态从由异常的功率放大器(如PA4)控制，调整为由无异常的功率放大器(如PA3)控制。
本申请实施例，通过检测功率放大器是否异常，进而对异常的功率放大器建立与同组功率放大器间的电流通路，可以应对功率放大器异常引起的扬声器运行状态异常。这样，将播放异常的扬声器对应的功率放大器，从目标功率放大器调整为同组功率放大器，可以使扬声器运行状态无异常，也就达到了目标状态。
示例性的，图11是本申请实施例提供的一种扬声器控制方法的流程图之一，该方法可以包括如下步骤：
S1101，启动声场检测；
S1102，确定扬声器信息；
S1103，根据扬声器信息，确定是否调整扬声器的运行状态；若调整，执行S1104， 若不调整，执行S1105；
S1104，执行与扬声器信息对应的运行状态调整方式；
S1105，输出扬声器报修提醒；
上述S1101至S1105与本申请图8至图10中作用相同的步骤类似，对于相同部分此处不再赘述，可以参见本申请图8至图10中的已有描述。区别在于本实施例中扬声器信息可以包括扬声器的当前状态信息和扬声器标识。
S1106，输出是否个性化调整的询问信息；
询问信息可以是音频、视频、文字等形式的信息，本申请对此不作限制。在一种可选的实施方式中，询问信息除了提示用户是否个性化调整外，还可以包括如下至少之一：播放异常的扬声器的标识、位置、异常原因等信息，以及音频播放装置所执行的运行状态调整方式(如图9或者图10执行的运行状态调整方式)。
S1107，是否接收到进行个性化调整的指示息；若接收到，执行S1108,；若未接收到，执行S1109；
进行个性化调整的指示信息可以是用户的语音指示、用户对询问信息上指示调整的控件的点击指令等等，本申请实施例对此不作限制。
S1108，展示个性化调整界面，个性化调整界面用于用户调整扬声器的声音效果参数；
个性化调整界面中可以展示运行状态调整方式包含的多个扬声器中至少一个的参数调整控件，该参数调整控件中可以预先设置用户可调整的参数数值和参数范围等组件，以引导用户进行合理的调整。
S1109，关闭询问信息，维持扬声器当前的运行状态。
音频播放装置在未接收到进行个性化调整的指示信息的情况下，表明用户认可音频播放装置执行的扬声器运行状态调整方式，因此，可以关闭询问信息，维持扬声器当前的运行状态。
本申请实施例，在可以调整扬声器运行状态的情况下，执行相应的调整方式也就是调整多个扬声器中至少一个的运行状态至目标状态，可以使用户感知到相应的调整效果。在此基础上，通过输出是否个性化调整的询问信息，可以告知用户扬声器的异常情况，并告知用户音频播放装置对该异常情况的处理方式，进而用户可以根据自身需求对音频播放装置执行的扬声器运行状态调整方式进行进一步调整优化，从而进一步降低扬声器的播放异常，提高用户体验。
可以理解的是，音频播放装置例如电子设备为了实现上述功能，其包含了执行各个功能相应的硬件和/或软件模块。结合本文中所公开的实施例描述的各示例的算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以结合实施例对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
